Area = pi*22 = 12.566 square cm to 3 d.p.
Area = pi*92 = 254.469 square cm to 3 dp
Area of ANY circle is (pi) x (radius)2 .
Area of circle: 36*pi = 113.097 square cm to 3 decimal places
36*pi
11.455 CM2
Area = pi*122
It is: pi*12*12 square cm
The area of a 3 cm circle is: 7.069 square cm
Area = pi*12 = pi cm2
Diameter = 12 cm so radius = 6 cm. Then area = pi*r2 = 36*pi = 113.1 cm2
The area of a circle with diameter 18.8 cm = the area of a circle with radius 9.4 cm = pi*r2 = 277.59 cm2, approx.The area of a circle with diameter 18.8 cm = the area of a circle with radius 9.4 cm = pi*r2 = 277.59 cm2, approx.The area of a circle with diameter 18.8 cm = the area of a circle with radius 9.4 cm = pi*r2 = 277.59 cm2, approx.The area of a circle with diameter 18.8 cm = the area of a circle with radius 9.4 cm = pi*r2 = 277.59 cm2, approx.
